Hi Dan,

There is another old HC technique that works well for me:

1. Create a single scrolling field with a non-proportional font (eg:
courier, monaco)
2. Pad text with trailing blanks and numbers with leading blanks to create
a fixed-format record for each line
3. Paint (in HC, position grid lines in RR) lines on the screen to create
4. Provide individual fields below the scroll field for entry of new items.

This solution may be low-tech, however it can also be a powerful
table-management tool.  I have written handlers to:

1.  Add a record to the table in ascending or descending order based on a
key value anwhere in the record.
2.  Select a record from the table based on key value
3.  Change any portion of a record
4   Delete a record based on key value
5.  Retrieve any portion of a record

If you would like to see how this translates visually, visit and look at the screen shots for
first-level screens under the Wines, Vessels, & Setup menus.
